I have a story like Rick's... my Grizzly 0700 baby slider was my first "real" piece of woodworking equipment, i.e. with a proper contactor switch and emergency stops. The saw would not start, messed with it for an hour before calling Grizzly... and yes, I had not released the stop button on the main switch

My contribution to this thread would be to warn people to not modify a machine like the OP did... an out of square base would have been reason enough to get the that part replaced.
